Guidelines for OSM-PH bulk data import

All planned imports should be announced to the talk-ph list.

Imports should NEVER delete or get in the way with local mapper's contributions, unless there is mutual agreement.

Data that will be imported will be provided to anyone willing to evaluate the quality of the data via a public download link. However, if the data holder have expressed that the "raw" shouldn't be distributed (due to some unfounded paranoia which I don't quite understand since it will be added to OSM anyway) another means to distribute data for evaluation will be made.

Community-consensus should be made before imports.

Another announcement will be made when consensus was achieved.

Another announcement after data import.

Update this page or provide a link to a documentation of the finished import.

Previous/Existing Imports

Schadow1 Expeditions

Background: Schadow1 Expeditions is a mapping and travel resource site for the Philippines documenting its Philippine expeditions, travel guides and mapping advocacy through GPS-based mapping funded through donations. GPS traces, POIs are contributed through various mapping consortium in the Philippines including OpenStreetMap.

WaypointsDotPH and RPMap

Background: WaypointsDotPH and RPMap are two of the earliest volunteer mapping projects in the Philippines using GPS-based mapping. Interestingly, both have similarities with OpenStreetMap; they basically use GPS traces to create Garmin maps. However, the approach is somewhat centralized. Contributors would send the traces to the mapmakers and the mapmakers prepare and distribute the output maps.

Initial discussion with the group is very encouraging they would like to share their years of accumulated data to OSM and at the same time create various applications using OSM data.

What they have:

Road network for the whole country

Lots and lots of POIs

GPS traces

Proposal for import:

Respective project maintainers will ask consent of all their contributors on the import process to OSM database. Only data from contributors who gave explicit consent will be imported.

Data review and assessment. Check for data integrity (copyright issues, etc.). Roads which are already in the OSM database will not be imported.

Subset data into manageable sizes.

Import data

Current status

Ed Garcia, maintainer of WaypointsDotPH, is adding roads, mostly provincial, using personal GPX traces and those contributed by WaypointsDotPH members.

The Naga City Government maintains a public domain WMS of the city including roads, landuse (2000), admin boundaries, building
footprints. I'm still coordinating to request the orginal data. In the meantime, use the WMS plugin in JOSM.
Link: http://gis.naga.gov.ph/nagacity_data.map

I downloaded the data from their WFS server into a GML file, applied gml2osm, fixed some small things on JOSM, and uploaded it all.

I would like some locals to re-check the road data, as it may have inaccuracies.

The layers imported were: roads, rivers, railroads, schools, hospitals. Layers pending are political boundaries (barangay?) and land use data, because of the complexity of working with relations for lots of adjacent areas.

Hon. Mayor Eugenio Jose V. Lacson,
Greetings Of PEACE!
My name is Emmanuel "Maning" Sambale and I am writing your good office
in behalf of Openstreetmap Philippines. Openstreetmap is an
international project whose aim is to create and provide free
geographic data for the whole planet. This is a volunteer project
currently with more than 90,000 users worldwide. The Philippines is
one of the active countries in South East Asia. We have a website and
a wikipage for your reference:
https://www.openstreetmap.org.ph/https://wiki.openstreetmap.org/index.php/WikiProject_Philippines
The current focus of mapping is Metro Manila. An example of our
current coverage is here:
https://www.openstreetmap.org/index.html?lat=14.594&lon=121.032&zoom=11
We are also expanding our coverage to other provinces in the country.
We believe San Carlos City as one of the progressive agro-industrial
center of Negros Occidental, should be extensively mapped as well.
The link below is the current map data for San Carlos City:
https://www.openstreetmap.org/?lat=10.4823&lon=123.4095&zoom=14&layers=B000FTF
As an initial step, we would like to gather secondary
information about San Carlos. May we request your office to provide us
with digital map data from the City's GIS department? We will take
care in converting the data to Openstreetmap and our local volunteers will regularly
update the information. We assure you that all updates and revisions will
be given back to the City Government.
Our group is also willing to provide technical assistance in preparing
webmap for your city's website just like Google Map but with better street data.
Thank you very much and we hope you can grant our request. Should there be any
clarifications, please send me message at emmanuel.sambale@gmail.com
Respectfully yours,
Emmanuel "Maning" Sambale
